AFR would be a measure of Air and Fuel for my guess. AFR if i had to guess stands for Air Fuel Ratio. I have been intending to get a set of SM needles and the video etc.. for my car. However what I'm really interested in is a rebuild kit that includes all the ZTherapy goodies like the shafts that use a ball bearing to reduce wear around the shaft. However I get confused easy with the whole deal, I would send mine over but the cost to send my cores and buy a set there is just out of my budget and besides I'd get more satisfaction from rebuilding them myself. Let me know what you wanna do Richard as I would like to get some myself (SM needles) Perhaps the bigger nozzles as well. We could order them together and perhaps save on shipping or whatever. I also know a guy here in Melbourne who knows what he is doing with SU's and is running them on his Stroked L28. I can get you in contact with him. Now that I'm on holidays I have some work planned for the car.. PS: I run out of puff around 5500rpm but i'm unsure as to what the problem is just yet. I also hear that remapping the distributor is a must with a larger camshaft profile. Gav

My sentiments exactly my insurance company has no idea about the L28 on my car or the bigger valves, cam , electronic ignition. There's just no point telling them, they will charge you more and i doubt for a second anyone would know who isn't into Z's or Datsun's. L24 L28 it just looks like another engine number. I only told them the obvious the wheels and exhaust. Vic roads wouldn't know any better either.

I have a set of 240z carbs Hitachi original equipment. Actually I have 3 sets of carbs 1 on my 240z, a set of British SU's and a spare set of 240z carbs. I don't know how much shipping for such an item would be (LD28 crank) but from America i was looking at $300-$400 just in shipping .... If you get your hands on an LD28 crank cheap maybe we could work something out

What i was getting at was for your application like a standard L24 engine. The DUAL SU's would be quite addequite unless you plan on doing some engine work i don't think you'd really notice much of a performance difference but then agian I've never tried it just read the theory. Gav

must only work in America either that or the windows calculator has disagreed with me once more!. Hehe I can see the last few digits are the same but that's it.

Nope you shouldn't under estimate it at all. I've seen alot of good things from the L-Series and I just love em'. I think Dual SU's would be all you want you don't wanna over-carb your motor.

New Zealand is so pretty. Makes me wanna take the Z there for a nice drive. Looks like it would have been fun , you seemed to keep up pretty well in the K have you done anything to your motor or is it the combo of L24 and camera lag that makes it look like you guys are going really fast .... I'm sure you had fun anyway!

When you put it that way

For interests sake can you please show us a picture of the "432-R Grille"? I am curious as I always thought there was more than 1 japanese grille but didn't know till i read the above? Gav

I'd say they should be ok. Good thing is U joints are fairly cheap so you won't loose out on too much if they can't be swapped.

Thanks for the tip i don't wanna go off topic here so maybe i will discuss it with you on viczcar forums or wa Zcars.

haha I hear you Mr C. I hear you indeed, BTW have you seen the new format for VicZcar? I'm pretty proud of it not finished yet just like WA Zcars

To me they are pretty similar but I can understand the old ones have their appeal they certainly looked good on the C10 I saw down here recently

This is a tough question because I have been told that after 75 you could not change the U joints infact you had to replace the entire shaft. This is in Australia BTW but GermanZ is yours a 280z? Do you know what year? I have never seen the type you can't change out as the latest Z i have owned was a 75 260z. The photo of the old ones you have provided is that of your car? If so they look like they are changable for sure. To my knowledge they all have the circlips the changeable ones anyway and you will need to remove those by getting a thin metal shaft such as a screwdriver and pressing it againt it while tapping the clips off with a hammer of some sort. Then you can press them out don't try hammering them out. As you will only damage the surrounding areas as I did. Take it to a shop for that and get them to press the new ones in. (Saves headaches). However please double check your shafts first if the picture you have sent is not your car. Perhaps also you can remove the shaft quite simple and provide a photo of the inside area so we can see the circlips. Just to be safe.
